are we in a low interest rate environment today? maintaining current policy a least three years or so should that be the prevailing environment assumption? >> you make a very important point in terms of the fact that the review was done not today but at a point with economic projections in july, over the summer. it is accurate that interest rates have dropped further than were built into the primary, actuarial view. there are two factors to that. home prices have performed better than were used in the actuarial. it would be significantly better today just on that one variable. the second point is that the view is a point in time that assumes we do no further fha business. one of the things that is artificial about it is that, when interest rates go lower, it assumes people pay off faster. that's accurate. typically path of that refinanced into -- half refinanced into fha. assume your clothes and down the fund, there are revenues that will come in not built and. budget, weident's will include the lower interest rates you described. w
